ENORMOUS iceberg close to BREAKING AWAY from Antarctica risking FOUR INCH sea rise

ONE of the biggest icebergs in the world is on the broke of breaking OFF from Antarctica, after a huge crack appeared.

The 5,000 square kilometre block of ice, which is one of the 10 biggest ever icebergs, could spark a four inch rise in sea levels if it rips away.

Scientists noticed a large rift in the Larsen C ice shelf in Western Antarctica had expanded suddenly last month.

Now they warn it is “hanging on by a thread” and could break away at any moment.

While the breakaway of this iceberg will not directly cause sea levels to rise, the experts behind the study from from Project Midas – a UK-based Arctic research group – believe it could leave the entire ice shelf it is attached to vulnerable to crumbling.
Project leader Professor Adrian Luckman, from Swansea University, said: "If it doesn't go in the next few months, I'll be amazed.
